[MODE FOR CARRYING OUT THE INVENTION]

[0012] Hereinafter, an electronic device according to various embodiments will be described with reference to the accompanying drawings. The term "user" used in various embodiments may indicate a person using an electronic device or a device (e.g., an artificial intelligence electronic device) using an electronic device.

[0013] FIG. 1 is a block diagram illustrating an electronic device 101 in a network environment 100 according to various embodiments. Referring to FIG. 1, an electronic device 101 in a network environment 100 may communicate with an electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or an electronic device 104 or a server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connecting terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the components (e.g., the connecting terminal 178) may be omitted from the electronic device 101, or one or more other components may be added in the electronic device 101. In some embodiments, some of the components (e.g., the sensor module 176, the camera module 180, or the antenna module 197) may be implemented as a single component (e.g., the display module 160).

[0014] The processor 120 may execute, for example, software (e.g., a program 140) to control at least one other component (e.g., a hardware or software component) of the electronic device 101 coupled with the processor 120, and may perform various data processing or computation. According to one embodiment, as at least part of the data processing or computation, the processor 120 may store a command or data received from another component (e.g., the sensor module 176 or the communication module 190) in volatile memory 132, process the command or the data stored in the volatile memory 132, and store resulting data in non-volatile memory 134.

For example, when the electronic device 101 includes the main processor 121 and the auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or to be specific to a specified function. The auxiliary processor 123 may be implemented as separate from, or as part of the main processor 121.

[0022] The sensor module 176 may detect an operational state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a state of a user) external to the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state. According to an embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0023] The interface 177 may support one or more specified protocols to be used for the electronic device 101 to be coupled with the external electronic device (e.g., the electronic device 102) directly or wirelessly. According to an embodiment, the interface 177 may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface.

[0024] A connecting terminal 178 may include a connector via which the electronic device 101 may be physically connected with the external electronic device (e.g., the electronic device 102). According to an embodiment, the connecting terminal 178 may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0025] The haptic module 179 may convert an electrical signal into a mechanical stimulus (e.g., a vibration or a movement) or electrical stimulus which may be recognized by a user via his tactile sensation or kinesthetic sensation. According to an embodiment, the haptic module 179 may include, for example, a motor, a piezoelectric element, or an electric stimulator.

[0027] The power management module 188 may manage power supplied to the electronic device 101. According to one embodiment, the power management module 188 may be implemented as at least part of, for example, a power management integrated circuit (PMIC).

[0028] The battery 189 may supply power to at least one component of the electronic device 101. According to an embodiment, the battery 189 may include, for example, a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell.

[0029] The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device 104 via the first network 198 (e.g., a short-range communication network, such as Bluetooth^™, Wi-Fi direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a fifth generation (5G) network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify or authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

[0030] The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module 192 may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module 192 may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module 192 may support various requirements specified in the electronic device 101, an external electronic device (e.g., the electronic device 104), or a network system (e.g., the second network 199). According to an embodiment, the wireless communication module 192 may support a peak data rate (e.g., 20 Gbps or more) for implementing 1eMBB, loss coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of downlink (DL) and uplink (UL), or a round trip of 1 ms or less) for implementing URLLC.

[0031] The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. According to an embodiment, the antenna module 197 may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, the antenna module 197 may include a plurality of antennas (e.g., array antennas). In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

[0032] According to various embodiments, the antenna module 197 may form a mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.

[0033] At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

[0034] According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the external electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device 101 may provide ultra low-latency services using, e.g., distributed computing or mobile edge computing. In another embodiment, the external electronic device 104 may include an internet-of things (IoT) device. The server 108 may be an intelligent server using machine learning and/or a neural network. According to an embodiment, the external electronic device 104 or the server 108 may be included in the second network 199. The electronic device 101 may be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology or IoT-related technology.

[0035] FIG. 2 is a diagram illustrating an example of a configuration of an electronic device according to an embodiment.

[0036] Referring to FIGS. 1 and 2, a processor 120 of an electronic device 101 according to an embodiment may be electrically connected to a memory 130 and a display module 160, and may include a video editing module 210 for editing a video (or a moving image). The video editing module 210 may be configured in a software type. The processor 120 may execute instructions stored in the memory 130 to implement the video editing module 210 illustrated in FIG. 2, and may control hardware (e.g., the display module 160, the audio module 170, or the camera module 180 in FIG. 1) associated with a function of a software module.

[0037] According to an embodiment, the processor 120 may, in response to a video editing request, obtain a video and execute a video editing application to display the obtained video in an execution screen (hereinafter, this is called a first screen) of the video editing application. The obtained video may be a video stored in the memory 130, a video received from an external device via the communication module 190, or a video filmed by the camera module 180.

[0038] According to an embodiment, the processor 120 may classify, based on a designated condition, image frames included in the video into at least one first type interval 211 (e.g., meaningful interval) and at least one second type interval 213 (e.g., meaningless interval). The first type interval 211 may include at least one image frame corresponding to the designated condition in the video. The second type interval 213 may indicate one or more image frames not corresponding to the designated condition.

[0039] According to an embodiment, the processor 120 may distinguish at least one main part (e.g., main scene) 221, based on image frames corresponding to at least one element included in the designated condition in the at least one first type interval 211. The designated condition may include at least one information among an action, a gesture, or an emotion for distinguishing the first type interval 211. The at least one information of the designated condition may include one or more different elements for extracting the at least one main part 221 (e.g., main scene) from the first type interval 211. For example, the action may include spinning, dancing, jumping, running, walking, a relaxing activity (e.g., play with pet), or eating, but is not limited thereto, and may further include various action-related elements. For example, the gesture may include hand shaking, clapping, or waving, but is not limited thereto, and may further include various gesture-related elements. For example, the emotion may include information (e.g., happy and surprise) indicating the length of the first type interval 211, information (speaking) indicating whether there is audio, and information (face zoom in) indicating person identification, and further include an element indicating a change in a scene during filming a scenery, but is not limited thereto, and may further include various emotion-related elements. For example, a play speed configured in the designated condition may be classified into 5-stage levels (e.g., very fast (4x: 1-3), fast (2x), medium (1x), slow (1/2x), and very slow (1/4x)), but is not limited thereto, and may be classified into different levels. For example, the information (e.g., happy and surprise) indicating the length (Nsec) of the first type interval 211 in the emotion may designate slow for the interval of 1-2 seconds, and designate fast for the interval after 2 seconds. For example, the information (face zoom in) indicating person identification in the emotion may designate slow for the interval of 1-2 seconds, and designate medium for the interval after 2 seconds. For example, the processor 120 may provide various theme effects through various combination of the action, the gesture, or the emotion of the designated condition.

[0040] According to an embodiment, the processor 120 may display, on the first screen, at least one menu which can be selected for video editing. For example, the at least one menu may be a user interface which displays a preview video according to at least one editing scheme (suggested effects). As another example, the at least one menu may be a button, an object, or a graphic element which can be selected by a user for video editing. The editing scheme (suggested effects) may be at least one scheme (e.g., at least one of a first editing scheme (dynamic speed), a second editing scheme (highlights), a third editing scheme (speed ramping), a fourth editing scheme (quick summary), or a fifth editing scheme (short clip)) for providing various editing results through changing of the speed of a video. For example, the first editing scheme (dynamic speed) may provide a preview video by collecting only first type intervals 211 identified in one video and changing the speed thereof. The second editing scheme (highlights) may provide a preview video by collecting only first type intervals 211 identified in one video and unchanging the speed thereof. The third editing scheme (speed ramping) may provide a preview video by including both the first type interval 211 and the second type interval 213 identified in one video, and changing the speed of the first type interval 211. The fourth editing scheme (quick summary) may provide a preview video by including both the first type interval 211 and the second type interval 213 identified in a video, maintaining the speed of the first type interval 211 (e.g., an extraction interval) at a first speed (e.g., 1x), and adjusting the speed of the second type interval 213 (e.g., a non-extraction interval) to a second speed (e.g., 4x). The fifth editing scheme (short clip) may provide a preview video in which the speed of only one interval among the first type intervals 211 identified in a video is changed.

[0041] According to an embodiment, when the at least one menu displayed on the first screen is selected, the processor 120 may switch to a speed editing screen for editing the play speed of the video, and control the display module 160 to display a video editing screen (hereinafter, this is called a second screen). The processor 120 may control the display module 160 to display a preview video corresponding to the selected menu, and display, on the second screen, an object (edit speed) (e.g., a button, a menu, a function, or a graphic element) for editing the speed of the preview video. The second screen may include objects for storing and sharing the preview video.

[0042] According to an embodiment, the processor 120 may, in response to a speed editing request generated by selection of a menu for speed editing, displayed on the second screen, may control the display module 160 to display a speed editing screen (hereinafter, this is called a third screen) for editing the play speed of the at least one main part 221 of the first type interval 211. The processor 120 may control the display module 160 to display a first speed adjustment object (speed of highlights area) on the third screen. When an expanding object for screen expanding displayed in an area adjacent to the first speed adjustment object is selected, the processor 120 may control to expand an area in which the first speed adjustment object is displayed, and may control the display module 160 to display, in the expanded area, speed adjustment objects for speed editing for at least one element included in the designated condition. When the expanding object for screen expanding displayed in the area adjacent to the first speed adjustment object is selected one more time, the processor 120 may reduce the expanded area, and control the display module 160 to display again the first speed adjustment object in the reduced area. The processor 120 may change the play speed of the at least one main part 221 included in the preview video by using the first speed adjustment object.

[0043] According to an embodiment, in a case where the second type interval 213 is included in the preview video, the processor 120 may control the display module 160 to further display, on the third screen, a second speed adjustment object (speed of non-highlights area) for editing the play speed of the second type interval 213. The second type interval 213 is different from the at least one main part 221 of the first type interval 211, and may include a non-main part 223.

[0044] According to an embodiment, the processor 120 may configure different play speeds for the first type interval 211 and the second type interval 213 identified based on the designated condition. For example, in a case where a plurality of first type intervals 211 are identified, the processor 120 may configure different play speeds for the plurality of first type intervals 211, respectively.

[0045] According to an embodiment, the processor 120 may set the play speed of the at least one main part 221 distinguished in the first type interval 211, to be different from the play speed of the at least one different part (e.g., non-main part 223). For example, in a case where a plurality of main parts 221 are distinguished, the processor 120 may set different play speeds for the plurality of main parts 221, respectively. For example, in a case where a plurality of main parts 221 are distinguished, the processor 120 may set the same play speed for main parts distinguished by the same element included in the designated condition among the plurality of main parts 221, and set the play speed of a different main part distinguished by a different element, to be different from the play speed for the main parts distinguished by the same element. For example, when image frames corresponding to two or more elements included in the designated condition are identified from the at least one main part, the processor 120 may divide the at least one main part into sub main parts corresponding to the two or more elements, respectively, and may set different play speeds for the sub main parts.

[0046] According to an embodiment, the processor 120 may control the display module 160 to display an edited preview video including the at least one main part 221 reflecting a set play speed. The processor 120 may control the display module 160 to display the edited preview video on the second screen and/or the third screen, and when a storage object displayed on the second screen and/or the third screen is selected, may store the edited preview video in the memory 130. When the edited preview video is stored, the processor 120 may control the display module 160 to display a preview video, among the at least one preview video displayed on the first screen, corresponding to the edited preview video such that the preview video reflects the edited preview video.

[0047] According to an embodiment, when image frames corresponding to two or more elements (e.g., walking of the action, and handshaking of the gesture) included in the designated condition are identified from a particular main part among the at least one main part 221, the processor 120 may divide the particular main part into sub main parts corresponding to the two or more elements, respectively. The processor 120 may set different play speeds for the sub main parts, and generate an edited preview video including the sub main parts reflecting the set different play speeds. For example, the processor 120 may control the display module 160 to display, on a screen obtained by expanding a fourth screen, an individual speed adjustment object for adjusting the play speed of a first sub main part corresponding to an element (e.g., hand shaking of the gesture). For example, the processor 120 may adjust the play speed (e.g., 3x) of the first sub main part included in the particular main part by using an individual speed adjustment object 451, and may maintain the play speed of a second sub main part at a play speed set for the particular main part.

[0059] FIG. 3 is a diagram illustrating an example of an operation method of an electronic device according to an embodiment of the disclosure. FIG. 4 is a diagram illustrating an example of an operation method of an electronic device according to an embodiment of the disclosure.

[0060] Referring to FIGS. 3 and 4, according to an embodiment, an electronic device 101 (e.g., an electronic device 101 in FIGS. 1 and 2) may, in operation 301, in response to a video editing request, execute a video editing application, obtain a video 401, and analyze the obtained video 401. The electronic device 101 may display the obtained video 401 on an execution screen (e.g., first screen 410) of the video editing application by the display module 160 (e.g., the display module 160 in FIG. 1). The obtained video may be a video stored in a memory (e.g., the memory 130 in FIG. 1), a video received from an external device via a communication module (e.g., the communication module 190 in FIG. 1), or a video filmed by a camera module (e.g., the camera module 180 in FIG. 1). The electronic device 101 may display, on the first screen 410, at least one menu 411 which can be selected for video editing. For example, the at least one menu 411 may be a user interface which displays a preview video according to at least one editing scheme (suggested effects). As another example, the at least one menu may be a button, an object, or a graphic element which can be selected by a user for video editing.

[0061] In operation 303, the electronic device 101 may classify image frames included in the video 401 into at least one first type interval 211a, 211b, and 211c (e.g., the first type interval 211 in FIG. 2) and at least one second type interval 213 (e.g., the second type interval 213 in FIG. 2), based on a designated condition in the analyzed video. The first type interval 211a, 211b, and 211c may include at least one image frame corresponding to the designated condition in the video. The second type interval 213 may indicate one or more image frames not corresponding to the designated condition.

[0062] In operation 305, the electronic device 101 may distinguish at least one main part 221a, 221b, and 221c (e.g., the at least one main part 221 in FIG. 2), based on image frames corresponding to at least one element included in the designated condition in the at least one first type interval 211a, 211b, and 211c.

[0063] In operation 307, the electronic device 101 may perform an operation for editing the play speed of the at least one main part 221a, 221b, and 221c. The electronic device 101 may set the play speed of the main parts 221a, 221b, and 221c to be different from that of at least one different part. The different part may be a non-main part (e.g., the non-main part 223 in FIG. 2) as a part which is included in the second type interval 213, and is different from the main parts 221a, 221b, and 221c of the first type intervals 211a, 211b, and 211c.

[0064] In operation 309, the electronic device 101 may display an edited preview video including the at least one main part 221a, 221b, and 221c reflecting the set play speed according to storage of a result of the edit according to the set play speed.

[0065] Referring to FIGS. 3 and 4 again, when operation 305 in FIG. 3 is performed, the electronic device 101 (e.g., the electronic device 101 in FIGS. 1 and 2) according to an embodiment may distinguish main parts 221a, 221b, and 221c in the one video 401, as illustrated in FIG. 4, based on image frames corresponding to at least one element included in the designated condition in the at least one first type interval 211a, 211b, and 211c. For example, when the designated condition is identified as, for example, an action through analysis of the video, the electronic device 101 may identify the first and third main parts 221a and 221c among the main parts 221a, 221b, and 221c as main parts corresponding to a first element (e.g., run), and identify the remaining second main part 221b as a main part corresponding to a second element (e.g., walk). The electronic device 101 may identify an editing scheme indicated by the selected menu 411 in the first screen 410. For example, when the selected menu 411 indicates a second editing scheme (dynamic speed), the plurality of second type intervals 213 may be excluded, only the plurality of first type intervals 211a, 211b, and 211c may be collected to generate a preview video 421 for editing, and the generated preview video 421 may be displayed on a video editing screen (e.g., second screen 420). The preview video 421 displayed on the second screen 420 may be output at the same speed as before the play speed is edited. As another example, when the selected menu 411 is at least one of a third editing scheme (speed ramping), a fourth editing scheme (quick summary), or a fifth editing scheme (short clip), only the plurality of first type intervals 211a, 211b, and 211c may be displayed without being collected, as the preview video 421 for editing. When editing of the play speed is completed, the preview video 421 may be displayed by being replaced with an edited preview video reflecting a result of the edit according to a set play speed.

[0066] Referring to FIGS. 3 and 4 again, when operation 307 in FIG. 3 is performed, the electronic device 101 (e.g., the electronic device 101 in FIGS. 1 and 2) according to an embodiment may, for example, when the at least one menu 411 displayed on the first screen 410 is selected, switch to the second screen 420 for editing the video 401, and display the second screen 420 on the display module 160. The electronic device 101 may display the preview video 421 (a dynamic speed video) corresponding to the selected menu 411, and display, on the second screen 420, an object (edit speed) 423 (e.g., a button, a menu, a function, or a graphic element) for editing the speed of the preview video 421. The electronic device 101 may display, on the second screen 420, a storage object (save) 425 for storing the preview video 421 and an object (share) 427 for sharing same. The preview video 421 (a dynamic speed video) may be a preview video before speed editing.

[0067] According to an embodiment, as illustrated in FIG. 4, in response to a speed editing request generated by selection of the object 423 for speed editing, displayed on the second screen 420, the electronic device 101 may display a speed editing screen (e.g., third screen 430) for editing the play speed of the at least one main part 221a, 221b, and 221c of the identified first type intervals 211a, 211b, and 211c. The electronic device 101 may display, on the third screen 430, a first speed adjustment object 431 (speed of highlights area) for editing the play speed of the at least one main part 221a, 221b, and 221c of the first type intervals 211a, 211b, and 211c included in the preview video 421. For example, the electronic device 101 may set the play speeds of the plurality of main part 221a, 221b, and 221c included in the preview video 421 by using the first speed adjustment object 431. For example, the electronic device 101 may set different play speeds for the first type intervals 211a, 211b, and 211c and the second type interval 213. For example, the electronic device 101 may collectively adjust the play speed of the first type intervals 211a, 211b, and 211c by 1x by using the first speed adjustment object 431.

[0068] According to an embodiment, in a case where the second type interval 213 is included in the preview video 421 as illustrated in FIG. 4, the electronic device 101 may display, on the third screen 430, a second speed adjustment object 433 (speed of non-highlights area) for editing the play speed of the second type interval. The electronic device 101 may adjust the play speed of the second type interval 213 by 4x by using the second speed adjustment object 433. As another example, if the preview video 421 is generated by collecting the first type intervals 211a, 211b, and 211c, and does not include the second type interval 213, the electronic device 101 may not display the second speed adjustment object 433 on the third screen 430.

[0069] According to an embodiment, the electronic device 101 may, as illustrated in FIG. 4, display, on the third screen 430, a storage object (save) 437 for storing a speed editing result. When the storage object437 displayed on the third screen 430 is selected, the electronic device 101 may store a result of the edit according to the configuration play speed. The electronic device 101 may replace the preview video 421 displayed on the second screen 420 with an edited preview video (edited movie), and display the edited preview video. When the storage object 425 displayed on the second screen 420 is selected, the edited preview video may be stored in the memory 130. For example, when the edited preview video is stored, the electronic device 101 may control the display module 160 to display the edited preview video instead of a preview video, among the at least one preview video displayed on the first screen, corresponding to the edited preview video. As another example, the electronic device 101 may display a preview video displayed on the first screen 410 in a thumbnail image type, and when a thumbnail image is selected, an edited preview video may be displayed (or reproduced) on the second screen 420 according to a set play speed.

[0070] According to an embodiment, the electronic device 101 may, as illustrated in FIG. 4, display, on the third screen 430, an expanding object 435 for screen expanding, displayed in an area adjacent to the first speed adjustment object 431. When the expanding object 435 is selected, the electronic device 101 may expand an area in which the first speed adjustment object 431 is displayed, and may display, on an expanded speed editing screen (e.g., fourth screen 440), speed adjustment objects for speed editing for at least one element included in the designated condition in the expanded area. When the expanding object 435 is selected one more time, the electronic device 101 may reduce the area expanded on the fourth screen 440, and display the third screen 430 displaying again the first speed adjustment object 431 in the reduced area. For example, the electronic device 101 may display, on the fourth screen 440, individual speed adjustment objects 441 and 443 for individually configuring the play speeds of the plurality of main parts 221a, 221b, and 221c for each of the elements (e.g., run and walk) included in the designated condition. For example, the electronic device 101 may collectively adjust the speed of the first main part 221a and the third main part 221c corresponding to the first element (e.g., run) by 1x by using the individual speed adjustment object 441. The electronic device 101 may adjust the speed of the second main part 221b corresponding to the second element (e.g., walk) by 3x by using the individual speed adjustment object 443. As another example, the electronic device 101 may set different play speeds for the plurality of main parts 221a, 221b, and 221c.

[0071] FIG. 5 is a diagram illustrating an example of a designated condition in an electronic device according to one embodiment.

[0072] Referring to FIG. 5, according to an embodiment, a designated condition may include at least one information among an action, a gesture, or an emotion for distinguishing the first type interval. The at least one information of the designated condition may include one or more different elements for extracting the at least one main part (e.g., main scene) from the first type interval. For example, the action may include spinning, dancing, jumping, running, walking, a relaxing activity (play with pet), or eating, but is not limited thereto, and may further include various action-related elements. For example, the gesture may include hand shaking, clapping, or waving, but is not limited thereto, and may further include various gesture-related elements. For example, the emotion may include information (e.g., happy and surprise) indicating the length of the first type interval, information (speaking) indicating whether there is audio, and information (face zoom in) indicating person identification, and further include an element indicating a change in a scene during filming a scenery, but is not limited thereto, and may further include various emotion-related element. For example, as illustrated in FIG. 5, a play speed set in the designated condition may be classified into 5-stage levels (e.g., very fast (4x: 1-3), fast (2x), medium (1x), slow (1/2x), and very slow (1/4x)), but is not limited thereto, and may be classified into different levels. For example, the information (e.g., happy and surprise) indicating the length (Nsec) of the first type interval in the emotion may designate slow for the interval of 1-2 seconds, and designate fast for the interval after 2 seconds. For example, the information (face zoom in) indicating person identification in the emotion may designate slow for the interval of 1-2 seconds, and designate medium for the interval after 2 seconds.

[0073] FIG. 6 is diagrams illustrating an example of editing a play speed of a video in an electronic device according to one embodiment.

[0074] Referring to FIG. 3, FIG. 4, and FIG. 6, according to an embodiment, when operations 303 and 305 in FIG. 3 are performed, the electronic device 101 (e.g., the electronic device 101 in FIGS. 1 and 2) may divide the video 401 into a plurality of first type intervals 211a, 211b, and 211c, and a plurality of second type intervals 213, as illustrated in (a) of FIG. 6, and identify the main parts 221a, 221b, and 221c in the plurality of first type intervals 211a, 211b, and 211c. The electronic device 101 may identify that the menu 411 selected on the first screen 410 is a first editing scheme (dynamic speed), and may generate a preview video 601 to be edited (e.g., the preview video 421 in FIG. 4) by excluding the second type intervals 213 and collecting only the plurality of first type intervals 211a, 211b, and 211c according to the first editing scheme (dynamic speed).

[0075] According to an embodiment, when operation 307 in FIG. 3 is performed, the electronic device 101 may set the main parts 221a, 221b, and 221c to have different play speeds, respectively, as illustrated in (b) of FIG. 6. For example, the electronic device 101 may adjust the play speed of the first main part 221a, among the main parts 221a, 221b, and 221c, to a speed (e.g., very fast (4x) for running in FIG. 5) designated for a first element (e.g., running), adjust the play speed of the second main part 221b to a speed (e.g., slow (1/2x) for walking in FIG. 5) designated for a second element (e.g., walking), and adjust the play speed of the third main part 221c to a speed (e.g., fast (2x) for running in FIG. 5) designated for the first element (e.g., running). As illustrated in (c) of FIG. 6, when each of a pre-start interval 611 and a post-end interval 613 is longer than a designated time (e.g., 1 s), the electronic device 101 may use the pre-start interval 611 and the post-end interval 613 as intervals in which the speed changes to allow a user to feel ramping. The pre-start interval 611 may be used in a case where there is a preparation motion before the main part is started, and the post-end interval 613 may be used in a case where there is an ending motion after the main part is ended. For example, the electronic device 101 may apply BGM in the first editing scheme (dynamic speed). For example, in a case where audio information is applied to the edited preview video, the electronic device 101 may configure a sound fade out state for a slow interval, and may configure a sound fade in state after the slow interval is ended.

[0076] FIG. 7 is a diagram illustrating an example of editing a play speed of a video in an electronic device according to one embodiment.

[0077] Referring to FIGS. 3, 4, and 7, according to an embodiment, when operations 303 and 305 in FIG. 3 are performed, the electronic device 101 (e.g., the electronic device 101 in FIGS. 1 and 2) may divide the obtained video 401 into a plurality of first type intervals 211a, 211b, and 211c, and a plurality of second type intervals 213, and identify the main parts 221a, 221b, and 221c in the plurality of first type intervals 211a, 211b, and 211c. The electronic device 101 may identify that the menu 411 selected on the first screen 410 is a second editing scheme (highlights), and may generate a preview video 701 (e.g., the preview video 421 in FIG. 4) by including all the plurality of first type intervals 211a, 211b, and 211c and second type intervals 213 according to the second editing scheme (highlights). The electronic device 101 may configure the plurality of first type intervals 211a, 211b, and 211c and second type intervals 213 to be all output at the same 1x speed, without editing the play speed according to the second editing scheme (highlights). The second editing scheme (highlights) may provide a preview video by collecting only the first type intervals identified in one video and unchanging the speed thereof.

[0078] FIG. 8 is a diagram illustrating an example of editing a play speed of a video in an electronic device according to an embodiment of the disclosure.

[0079] Referring to FIGS. 3, 4, and 8, according to an embodiment, when operations 303 and 305 in FIG. 3 are performed, the electronic device 101 (e.g., the electronic device 101 in FIGS. 1 and 2) may divide the obtained video 401 into a plurality of first type intervals 211a, 211b, and 211c, and a plurality of second type intervals 213, and identify the main parts 221a, 221b, and 221c in the plurality of first type intervals 211a, 211b, and 211c. The electronic device 101 may identify that the menu 411 selected on the first screen 410 is a third editing scheme (speed ramping), and may generate a preview video (e.g., the preview video 421 in FIG. 4), which includes all the plurality of first type intervals 211a, 211b, and 211c and second type intervals 213, and has undergone play speed editing, according to the third editing scheme (speed ramping). The third editing scheme (speed ramping) may provide a preview video by including both the first type interval and the second type interval identified in one video, and changing the speed of the first type interval.

[0080] According to an embodiment, when operation 307 in FIG. 3 is performed, the electronic device 101 may collectively adjust the play speed of the first main part 221a and the third main part 221c among the main parts 221a, 221b, and 221c to a speed (e.g., very fast (4x) for running in FIG. 5) designated for a first element (e.g., running) because the same main parts both correspond to the first element (e.g., running), and adjust the play speed of the second main part 221b to a speed (e.g., slow (1/2x) for walking in FIG. 5) designated for a second element (e.g., walking). The play speed of the second type interval 213 may be configured to be maintained at 1x.

[0081] FIG. 9 is a diagram illustrating an example of editing a play speed of a video in an electronic device according to one embodiment.

[0082] Referring to FIGS. 3, 4, and 9, according to an embodiment, when operations 303 and 305 in FIG. 3 are performed, the electronic device 101 (e.g., the electronic device 101 in FIGS. 1 and 2) may divide the obtained video 401 into a plurality of first type intervals 211a, 211b, and 211c, and a plurality of second type intervals 213, and identify the main parts 221a, 221b, and 221c in the plurality of first type intervals 211a, 211b, and 211c. The electronic device 101 may identify that the menu 411 selected on the first screen 410 is a fourth editing scheme (quick summary), and may generate a preview video (e.g., the preview video 421 in FIG. 4), which includes all the plurality of first type intervals 211a, 211b, and 211c and second type intervals 213, and has undergone editing of a play speed, according to the fourth editing scheme (quick summary). The fourth editing scheme (quick summary) may provide a preview video by including both the first type interval and the second type interval identified in a video, maintaining the speed of the first type interval (e.g., an extraction interval) at 1x, and adjusting the speed of the second type interval (e.g., a non-extraction interval) by 4x. For example, the electronic device 101 may apply BGM in the fourth editing scheme (quick summary).

[0083] FIG. 10 is a diagram illustrating an example of editing a play speed of a video in an electronic device according to one embodiment.

[0084] Referring to FIGS. 3, 4, and 10, according to an embodiment, when operations 303 and 305 in FIG. 3 are performed, the electronic device 101 (e.g., the electronic device 101 in FIGS. 1 and 2) may divide the obtained video 401 into a plurality of first type intervals 211a, 211b, and 211c, and a plurality of second type intervals 213, and identify the main parts 221a, 221b, and 221c in the plurality of first type intervals 211a, 211b, and 211c.

The fifth editing scheme (short clip) may provide a preview video in which the speed of only one interval among the first type intervals identified in a video is changed.

[0085] According to an embodiment, when operation 307 in FIG. 3 is performed, the electronic device 101 may adjust only one main part of the main parts 221a, 221b, and 221c to a designated speed. For example, the electronic device 101 may adjust the play speed of the first main part 221a to a speed (e.g., very fast (4x) for running in FIG. 5) designated for the first element (e.g., running). As another example, the electronic device 101 may adjust the speed of the second main part 221b to a speed (e.g., slow (1/2x) for walking in FIG. 5) designated for the second element (e.g., walking). As yet another example, the electronic device 101 may adjust the play speed of the third main part 221c to a speed (e.g., very fast (4x) for running in FIG. 5) designated for the first element (e.g., running). For example, information of a designated condition for an interval provided as a clip may be an action and an emotion, the electronic device 101 may configure, according to the length of a clip, slow for a clip with 1-2 seconds, fast for a clip with 2.1-8 seconds, and very fast for a clip with 8.1 seconds or longer. When a video editing operation is performed, in a case where the first editing scheme (dynamic speed) and the fifth editing scheme (short clip) are the same, the electronic device 101 may not provide the fifth editing scheme (short clip). For example, the electronic device 101 may not apply background music (BGM) in the fifth editing scheme (short clip).

[0087] Referring to FIGS. 3 and 11, according to an embodiment, when operations 303 and 305 in FIG. 3 are performed, the electronic device 101 (e.g., the electronic device 101 in FIGS. 1 and 2) may divide the obtained video 401 into a plurality first type intervals 211a, 211b, and 211c, and a plurality of second type intervals 213, and identify the main parts 221a, 221b, and 221c in the plurality of first type intervals 211a, 211b, and 211c. The electronic device 101 may identify that some of the main parts 221a, 221b, and 221c include image frames corresponding to different elements. For example, the electronic device 101 may identify that the main parts 221a and 221c both correspond to the first element (e.g., running of the action), or correspond to different elements (e.g., running and jumping of the action), respectively. For example, the electronic device 101 may identify that there are image frames corresponding to a third element (e.g., hand shaking of the gesture) in the second main part 221b. The electronic device 101 may classify, into sub main parts 1111, the image frames corresponding to the third element, which are identified in the second part 221b. The electronic device 101 may further identify sub main parts in identified main parts according to a reference condition as illustrated in FIG. 5 so as to provide 2-step video speed changes.

[0088] Referring to FIGS. 3, 4, 11, and 12, according to an embodiment, the electronic device 101 may, in response to a speed editing request generated by selection of the object 423 displayed on the second screen 420, may display, on the third screen 430, the first speed adjustment object 431 (speed of highlights area) for editing the play speed of at least one main part of the first type intervals 211a, 211b, and 211c included in the preview video 421. For example, the electronic device 101 may set the play speeds of the plurality of main part 221a, 221b, and 221c included in the preview video 1101 by using the first speed adjustment object 431. For example, the electronic device 101 may set different play speeds for the first type intervals 211a, 211b, and 211c and the second type interval 213. For example, the electronic device 101 may collectively adjust the play speed of the first type intervals 211a, 211b, and 211c by 1x by using the first speed adjustment object 431. In a case where the second type interval 213 is included in the preview video 421, the electronic device 101 may display, on the third screen 430, the second speed adjustment object 433 (speed of non-highlights area) for editing the play speed of the second type interval. The electronic device 101 may adjust the play speed of the second type interval 213 by 4x by using the second speed adjustment object 433. As another example, if the preview video 421 is generated by collecting the first type intervals 211a, 211b, and 211c, and does not include the second type interval, the electronic device 101 may not display the second speed adjustment object 433 on the third screen 430. The electronic device 101 may display, on the third screen 430, the storage object 437 for storing a speed editing result. When the storage object 437 displayed on the third screen 430 is selected, the electronic device 101 may store a result of the edit according to a configuration play speed. The electronic device 101 may replace the preview video 421 displayed on the second screen 420 with an edited preview video, and display the edited preview video. When the storage object 425 displayed on the second screen is selected, the edited preview video may be stored in a memory (e.g., the memory 130 in FIG. 1). For example, when the edited preview video is stored, the electronic device 101 may display, on the display module 160, the edited preview video instead of a preview video, among the at least one preview video displayed on the first screen, corresponding to the edited preview video. As another example, the electronic device 101 may display a preview video displayed on the first screen 410 in a thumbnail image type, and when a thumbnail image is selected, an edited preview video may be displayed (or reproduced) on the second screen 420 according to a set play speed.

[0089] According to an embodiment, the electronic device 101 may display, on the third screen 430, the expanding object 435 for screen expanding, displayed in an area adjacent to the first speed adjustment object 431. When the expanding object 435 is selected, the electronic device 101 may expand an area in which the first speed adjustment object 431 is displayed, and may control the display module 160 to display, on the expanded speed editing screen (e.g., fourth screen 440), speed adjustment objects for speed editing for at least one element included in the designated condition in the expanded area. When the expanding object 435 is selected one more time, the electronic device 101 may reduce the area expanded on the fourth screen 440, and display the third screen 430 displaying again the first speed adjustment object 431 in the reduced area. For example, the electronic device 101 may display, on the fourth screen 440, individual speed adjustment objects 441 and 443 for individually configuring the play speeds of the plurality of main parts 221a, 221b, and 221c for each of the elements (e.g., run and walk) included in the designated condition. For example, the electronic device 101 may collectively adjust the speed of the first main part 221a and the third main part 221c corresponding to the first element (e.g., run) by 1x by using the individual speed adjustment object 441. The electronic device 101 may adjust the speed of the second main part 221b corresponding to the second element (e.g., walk) by 3x by using the individual speed adjustment object 443. As another example, the electronic device 101 may set different output speeds for the plurality of main parts 221a, 221b, and 221c.

[0090] According to an embodiment, the electronic device 101 may display, on the fourth screen 440, a storage object (save) 447 for storing the edited preview video. When the storage object 447 is selected, the electronic device 101 may store an edited preview video reflecting play speeds adjusted using the individual speed adjustment objects 441 and 443 on the fourth screen 440.

[0091] According to an embodiment, the electronic device 101 may identify that there are image frames 461 corresponding to a different third element (e.g., hand shaking of the gesture) in the second main part 221b. The electronic device 101 may display, on the fourth screen 440, an expanding object 445 for screen expanding, displayed in an area adjacent to the individual speed adjustment object 443. When the expanding object 445 is selected, the electronic device 101 may, as illustrated in FIG. 12, display a screen (e.g., fifth screen 450) obtained by expanding a partial area (e.g., an area in which the individual speed adjustment object 443 is displayed) of the fourth screen 440. The electronic device 101 may further display an individual speed adjustment object 451 for adjusting the play speed of the first sub main part 1111 corresponding to the different third element (e.g., hand shaking of the gesture) on the fifth screen 450. According to an embodiment, the electronic device 101 may display, on the fifth screen 450, a storage object 457 for storing the edited preview video. When the storage object 457 is selected, the electronic device 101 may store an edited preview video reflecting play speeds adjusted using the individual speed adjustment objects 441, 443, 451, and 433 on the fifth screen 450. When the expanding object 445 is selected again, the electronic device 101 may return to the fourth screen 440 again. For example, the electronic device 101 may adjust the play speed (e.g., 3x) of the first sub main part 1111 included in the second main part 221b by using the individual speed adjustment object 451. The play speed of a second sub main part 1113 may be maintained to the play speed set for the second main part 221b.

[0092] The speed adjustment objects 431 and 433 and the individual speed adjustment objects 441, 443, and 451 are illustrated in a bar type in FIGS. 4 and 11 described above, and may be illustrated as a user interface adjusted by a user's input, or result information automatically adjusted in the electronic device 101. The speed adjustment objects 431 and 433 and the individual speed adjustment objects 441, 443, and 451 may be replaced to be in a graph type as illustrated in FIG. 12, but are not limited thereto and may be illustrated by various types of graphic elements.
